About the Role

We are looking for a Staff Backend Engineer to join our Identity Graph team and lead the development of our next-generation Entity Resolution API. This critical component of our platform powers entity linking through advanced search and graph-based intelligence. You’ll work at the intersection of large-scale data processing, real-time search infrastructure, and machine learning-based ranking systems.

You’ll be responsible for designing and building both streaming and batch data pipelines that feed into a low-latency Search Cluster (ElasticSearch/Vespa), and for developing scalable, cloud-native APIs on top of this cluster that deliver high-accuracy, high-speed entity linking results. You will collaborate cross-functionally with Data Science, Infrastructure, and Product teams to design scalable APIs, build robust pipelines, and ensure reliable, observable, and performant distributed systems.

What You’ll Do

• Lead architecture and development of high-performance, cloud-native Entity Resolution APIs.

• Design and implement batch and streaming data pipelines using tools like Kafka, SQS, and Spark to build and update the underlying search index.

• Build and maintain low-latency search APIs powered by ElasticSearch or Vespa to support real-time entity linking.

• Collaborate with data scientists to integrate and deploy ranking models to improve search result quality.

• Own the end-to-end lifecycle of applications deployed on Kubernetes, from development and CI/CD to monitoring and scaling.

• Conduct performance tuning and debugging of search systems under high throughput and low-latency requirements.

• Develop tools and metrics to benchmark search quality and system performance.

• Partner with cross-functional teams in data science, infrastructure, and product to deliver reliable, scalable solutions.

• System Design: Lead design discussions and planning for backend services that incorporate model inference, SQL/NoSQL and Graph databases.

What We’re Looking For

• 8+ years of backend software engineering experience, with 1+ years in a staff/principal-level role.

• Expertise in search technologies like ElasticSearch or Vespa, including deployment, tuning, and query optimization.

• Strong cloud-native experience, especially with AWS services like S3, SQS, Lambda, and Kafka.

• Proven ability to design, build, and maintain distributed systems handling high-volume data streams and real-time requirements.

• Deep knowledge of Kubernetes-based application development and deployment.

• Strong proficiency in one or more backend programming languages (Java, Scala, Go, Python, etc.).

• Experience benchmarking and deploying machine learning models (ranking, reranking, classification) into production search pipelines.

• Strong problem-solving, communication, and collaboration skills.

• Familiarity with SQL/NoSQL and Graph databases

Bonus Skills

• Experience with knowledge graphs, entity resolution, or identity data.

• Prior work with real-time event processing frameworks.

• Hands-on experience integrating GraphQL APIs over complex data systems.

• Exposure to privacy, security, or compliance requirements in identity or fintech environments.

• Knowledge of Graph Databases and Open Cypher Queries

• Familiarity with data pipeline frameworks (e.g., Apache Beam, Spark Structured Streaming) is a plus.
